Being wrong isn’t inherently bad so long as you’re actually open-minded and willing to receive new information, critically process it and adapting your mode of thinking to the new information.
The problem these days with some people is that because of the internet hammering us with information and opinions, the discrediting of the media on both sides of the political spectrum as well as our knowledge of advertising and how our attention is pulled in and manipulated to a certain extent, we as a culture have become more suspicious and (we think), discerning as it relates to trusting incoming information, which I believe only further cements our opinions, for better or worse.
This is also compounded by many people creating their own information echo chambers where they only trust sources that inform their preconceived opinions and sometimes lose the ability to adapt their thinking when information that contradicts what they consistently see and believe enters their orbit, especially from “other” sources. Some stuff then gets overly filtered and some, none at all.
Some people simply deny facts, dismiss them, diminish them, resent them, or find some sort of logical fallacy they think they can apply, or simply choose to remain ignorant (that is to say, lacking all or any relevant information, but not necessarily the intelligence to understand it).
Of course, many of us have social media, comment sections and other places to sound off on, so incorrect information both from stories generated by outlets with agendas as well as those that comment on and disseminate them, usually buttressing their arguments with “it’s just my opinion,” can easily create a perfect storm of “wrong” which happens all too frequently.
The sad part is that everyone’s so inundated with information, whether correct, incorrect or partially correct, that discerning what’s real, what’s not, what’s important, what’s not, what’s really bad or kind of bad or not bad at all or what’s right or wrong or where our focus should be, etc becomes a near herculean task, and this is for the people that actually bother to seek truth.
Many don’t for a variety of reasons. Maybe they think they’ve already found it, maybe they care enough to speak, but don’t care enough to research. Maybe they don’t like who’s delivering the information or think nuance or gray area is a sign of capitulation. Honestly, some people feel certain information or amounts of it is elitist… Any of those plus what’s been previously mentioned, plus many more can keep people from absorbing new information or correcting something that they’ve had incorrect for any amount of time.
So yeah, I do think that being wrong can be a bad thing, but it’s what you do with that incorrect information or how you act with it as well as how you react to correct information, etc that really determines what’s wrong with being wrong, or rather, how wrong (or damaging) it is to be wrong.
Just my two cents
